CHICAGO, ILLINOIS, ASSI GNORS, BY MESNE ASSIGNMENTS, TO ZEROZONE, INCORPORATED, OF CHICAGO, ILLINOIS, A CORPORA- 'IION OF DELAWARE COMPRESSOR MOUNTING Application. filed Karen S,

This invention relates to mechanical refri erators,-and has to do more particularlywit the mounting of the compressor unit.

' ln'mechanlcal refrigerators of known type, which employ an electric motorfor driving the compressor, a certain amount of vibration is unavoidable. This vibration is apt to be transmitted to the frame and easing of the refrigerator structure, resulting in undesirable noise. In mechanical refrigerators it is of the compressor unit.

eration of such unit. A further object is to provide means whereby metallic contact between the supporting means for the compressor unit and the elements of the frame or casing of the refrigerator is prevented. A

"'- further object is to provide supporting means of the character stated of simple and inexpensive construction and which is adapted to I permit ready removal and replacement of the condenser and associated parts as a unit. 7 Further objects and advantages of the invention will appear from the detailed descrip- In the drawing:

Figure 1 is a horizontal sectional View throughthe lower portion of a mechanical refrigerator of .known construction, the compressor unit and associated parts being shown in plan and Figure 2'is a sectional view,'on an enlarged scale, taken substantially on line 22 of Figure 1.

We have illustrated our invention as applied to a mechanical refrigerator comprising a sheet metal casing 1 suitably secured, ad-

j acent its lower end, to an angle iron frame 2 of rectangular shape in plan.

A pair of angle rails 3 are riveted or otherwise suitably securedto frame 2 and extend across the same from front to back of the casing. These rails are suitably spaced for reception of a rectangular base plate 4: upon which is mounted the compressor unit. This unit comprises a compressor 5, condensing coil 6, an electric motor 7 a thermostatic switch 8, and associated parts. The compressor unit is, in general, of known construction and is disclosed more fully in our copending application for compressor mounting, Serial No. 231,875, filed November 8, 1927. The compressor unit may be of any suitable or preferred t pc and need not be further illustrated or escribed here, it being sufficient to note that a suitable ty e of compressor unit is mounted upon the ass plate-4.

The base 4 is preferably inthe form of a casting and comprises a top plate 9 of rectangular shape having a depending peripheral flange 10 and provided at each corner with a depending boss 11. The bosses 11 are each suitably cored out from its lower end to rovide a socket comprising a lower cylln rical portion 12 and an upper upwardly tapering portion 13. The lower portion 12 of each boss receives a thick rubber collar 14 disposed about a bolt 15 which passes through lower flange 3a of rail 3, a nut 16 being screwed onto the lower end of this bolt.

A fibre washerl7 is confined between head 18 of the bolt and the upper end of collar 14. it being noted that the washer 17 is of an appreciably greater diameter than the head 18 of the bolt. '.n upwardly tapering cushion member, in the form of a plug 19 formed of rubber or other suitable cushioning material,

fits into the upper portion 13 of the socket and has its under face concave as at 20. An expansion coil spring 21 seats upon the upper end of collar 14, the lower end of this spring extending about the fibre washer 17 in contact with the circumferential surface thereof. The upper end of this spring seats in the concave under surface of the rubber plug 19. I

It will be noted that the rubber collar 14 21 and the boss 11 of the head of the bolt is v be also prevented. The springs 21 are well adapted for supportin ase 4 and the compressor unit mounted t ereon in such manner as to permit of suflicient yielding thereof to efiectivel damp out vibrations due to operation of t e compressor.

This damping action of the sprin is so plemented by the cushionin efiect o the ru er collar 14 and the rub r plug 19. We find that it is not practicable to support the base 4 b rubber cushioning members alone, since ru her under compression, has comparatively slight resiliency. Also, rubber is not well adapted, mechanically, for supporting a structure of this character. By our construction we obtain the benefit of the cushionin efl'ect of the rubber as well as the bene, t of the relativel great resiliency of the supportin spring 1.

The means or supporting the base 4 is of comparatively sim e construction, and any of the elements of his supporting means can be readily removed and replaced as re uired. It is also to be noted that the base 4 isfree from thes ring 21 so that the com ressor unit, inclu mg the base 4, can be rea il removed from t e casing 1 and replaced erem For this urpose the casing is provided with a remova 1e panel 23 which is removably secured in the casing in a known manner. By raising the base 4 slightly the entire compressor unit can be removed through the opening rovided by the removal of panel 23 and can replaced through such opening.

What we claim is:

1. In combination, a supporting member, a base disposed above the supporting member and provided with a downwardly opening socket, a cushion member secured to the su porting member and projecting into said socket to limit the lateral motion of the base on the supporting member, a cushion member disposed within the socket, and a cushion spring confined between the two cushion members for supporting the. base upon the support, said'sprin bein spaced away fromthe surrounding wa l of t e socket. J

2. In combination, a supporting member, a base member above the supporting member and having a downwardly opening socket, a cushion member seated upon the supportmg member and extending into the lower on of said socket, a bolt extending through 1,ssa,aso
